Perimeter of Stent Design

• Other stent designs are more limited in their side branch cell opening. Also, with many stent designs, when opening a cell the concentric strut rings accordian on top of each other. This overlapping could delay endothelialization and impede blood flow at the ostium.

R stent cells have a perimeter of 17.9mm
The perimeter is the same for unexpanded and expanded cells
